Experimental data indicate that GA-CDA-RM enhances the high-temperature rheological properties, rutting resistance, and low-temperature crack resistance of the asphalt binder while reducing the leaching of heavy metal ions in RM. Leaching concentrations of six heavy metals decreased to 10 μg/L, with significant reductions in four additional ions. At 46°C, asphalt binders modified with a 4% mass fraction of GA-CDA-RM demonstrated substantial improvements: the composite modulus (<i>G</i>*) increased by 94.55% compared to styrene–butadiene–styrene (SBS) modified asphalt (MA), while both storage modulus (<i>G</i>′) and loss modulus (<i>G</i>″) increased by 96.99% and 93.88%, respectively. At 64°C and 0.1 kPa, the deformation recovery rate (<i>R</i>) of 4% GA-CDA-RM@MA improved by 50.88% compared to MA, and at −12°C, the <i>m</i>-value increased by 14.8%. This study introduces a novel approach for the environmentally sound treatment and reuse of RM, providing both guidance and a theoretical framework for its recycling endeavors.

To solve these problems, the researchers developed a composite material consisting of PBSeT and zinc gluconate (ZG) to improve the performance of PBSeT through the synergistic effect of ionic and hydrogen bonds. Notably, the tearing strength of the PBSeT/ZG-3 composite exhibits a remarkable increase of 48.7% relative to PBSeT alone, while the puncture load is enhanced by 25.3%. Furthermore, XRD and TG analyses indicate that the incorporation of ZG has a negligible impact on the crystallinity and thermal stability of the composites. Interestingly, the enzymatic degradation properties are significantly improved with increasing ZG content, and the enhanced hydrophilicity imparted by ZG results in a reduction in the water contact angle of the composite materials. In conclusion, the integration of ZG significantly enhances the puncture resistance, tear strength, and biodegradability of PBSeT.
